Abstract

The present application discloses a JAR upgrading method and apparatus. The method comprises that a client sends JAR file information of its own to a server, when it is determined that the JAR file of the client needs to be updated according to the JAR file information, the server returns the JAR update file, and the client carries out JAR file upgrade after receiving the JAR update file; or the server collects the JAR file information of the client and when the JAR file of the client needs to be updated, sends a JAR upgrade command to the client, and after receiving the JAR upgrade command, the client downloads the JAR update file to carry out JAR file upgrade. Thus, instead of manually uploading the JAR upgrade file, automatic upgrade of the JAR file is realized; and the client loads the class in the JAR update file into the JVM, and the original class in the JVM is replaced with the class in the JAR update file so as to implement the hot update of the JAR file, so that the JAR file upgrade is completed without rebooting the system.

Description

technical field [0001] The invention relates to the technical field of software, in particular to a JAR upgrading method and device. Background technique [0002] JAR (Java Archive, Java Archive) is a platform-independent file format that allows many files to be combined into one compressed file. The JAR file format is based on the popular ZIP file format, so files in the JAR file format are also called JAR packages. Unlike ZIP files, JAR files are not only used for compression and distribution, but also for deployment and packaging of libraries, components, and plug-ins, and can be directly used by tools such as compilers and JVM (Java Virtual Machine, Java Virtual Machine) . [0003] In software testing or project product integration, JAR upgrades are often faced. Usually JAR upgrade is to upload the JAR upgrade file to the system, modify the class (class) file in the JVM offline according to the JAR upgrade file, because the class in the JVM changes when offline, it is...
